ATTACHMENT FOR PRINTING PRESSES.

Application filed May 28, 1927. Serial No. 195,050.

This invention relates to new and useful improvements in attachments forprintmg presses, and more particularly to an attachment which especiallyis adapted for use 1n connection with printing presses which are usedfor job printing, although it-may be used in connection with diflerenttypes of presses.

One of the objects of my invention is the r provision of an attachmentwhich is particularly adapted for use in receiving the printed I sheetsas they are discharged fromthe press and is so constructed as to permita great number of printed sheets to be deposited thereon before it isnecessary to remove them, thus an' ordinary printing job can be runthrough the press before it is necessary to rempglve the printed sheetsfrom the receiving ta e.

Another object of my invention is the pro-' vision of a receiving tableprovided with improved jog ing means whereby thaprinted sheets may eevenly stacked and retained in this manner until removed from the table;

A further object of my invention is the pro vision of a receiving devicewherein the ogging members and the movable parts attached thereto are soarranged that they may be raised upwardly from the table to permit readyremoval of the printed sheets.

A still further object of the invention is the rovision of a simplyconstructed device which can be quickly and readily placed in positionand attached to the delivery mechanism of a printing ress to receive theprinted sheets in great num ersand neatly stacked, so that at times anordina job of printing may be completed before it is necessary to emptythe table.

With the above and other objects in view the invention consists in thenovel features 0 construction, the combination and arrangement of partshereinafter more fully set forth, pointed out in the claims and shown inthe ac- 45, companying drawings, in which Figure 1 is a side elevationof my improved device with parts thereof broken away and shown insection. a q

Figure 4 is a view similar to Figure 3, with parts thereof in raisedposition.

Fgure 5 is a sectional view taken on the line 5-5 of Figure 2.

Figure 8 is a detail perspective view of one end of one of the movableside bars, and

Figure 9 is a detail perspective view of the pivot socket for one of themovable bars.

As stated heretofore, the device is particularly adapted for attachmentto the delivery end of a printing press, but it may be used whereverfound efficient. The device is supported by a suitable frame whichcomprises the upright angle bars 1, one at each corner of the frame,which are connected at the lower ends by the plate'2, which hasdownturned flanges 3 adapted to be bolted or otherwise secured tothebars l. Intermediate theends ofthe bars 1 is positioned a stop platform4' held in'place by the angular brackets 5 .which are secured to theunder surface of the platform and the angle bars.

A movable platform 7 is arranged in the frame and guided in its verticalmovement by the angle bars 1. Attached to the lower" face of theplatform 7 is a cylinder member 8 which is movable through an opening-9in the stop platform 4 and received throughits lower end is anadjustable guide plunger 10. Arranged in the cylinder member 8 is a coilspring 11, the upper end of which is attached to a cross pin 12 and itslower end bearing upon an annular flange 13 at the upper end of theguide plunger. The tension of the spring 11 may be readily adjusted bythreadm bearing collar 14 on the plate 2. I

Three sides of the frame at the upper end thereof are closed by anangular angle bar 15, secured to the barsl by suitable brackets and anangle bar 16 pivoted-t6 one of the angle bars 1 at 17. Ari'anged beneaththe bar15 and movable in guides 18 on the bars 1 is a movable angle bar19, one end of which is pivotnlly connected with a rocking link 20 whilethe other end rests in a transverse recess 21 formed in a movable bar22, which is slidably mounted in a pivoted guide collar 23. This guidecollar 23 is pivoted to one of the angle bars 1 at a point adjacent thepivot 17 of the bar 16. The outer end of the angle bar 19 is movablymounted in a slotted guide plate 24 attached to one of the bars 1 so asto support the outer end of the bar 22 and mainthe lower end of theguide plunger in a I The upper ends of the blocks are formed ends 31formed with apertures to slidablyv receive the bars 32. The blocks 28are each formed with a transverse opening to receive the bars 32 and theblocks carry thumb screws 33 for binding engagement with the bars 32 toretain them in various adjusted positions.

with reduced parts 34 movable in the slots 35 in the longitudinal plates30 so that as the roller 27 moves in the slot 26 the part 34 will movein the slot 35.

Attached to the inner ends of the bars 32 are the jogger or guide plates36, the forward ends of which are curved outwardly as at 37 to uide therinted sheets therebetween. Thus it Will e apparent that as the rocklink 20 is connected to a reciprocating arm 38, which may be connectedto a movable part of the press, the plates 36 are moved apart or awayfrom each other prior to the depositing of a printed sheet on theplatform 7 and after the sheet has been deposited the plates 36 aremoved inwardly toward each other and engage the sheet for properlypositioning the same on the platform.

A guide or jogger plate 39 is provided at the end of the frame farthestfrom the press and acts in conjunction with the plates 36 whenstraightening the sheets deposited on the platform 7. The plate 39 hasan arm 40 attached thereto, the outer end of which is extended throughthe apertured ends of a U- shaped clamp 41 attached to the horizontalportionv of the bar 19. The clamp 41 carries a set screw 42 for bindingengagement with the bar 19 so that the arm 40 can be clamped to the bar19 in various adjusted positions.

It will be apparent from the foregoing that the device is positionedadjacent the delivery end of a printing press and so arranged that theopen side of the upper end of the frame isnext to the delivery guidebars 43. The bar 19 is operatively connected to the reciprocating arm 38by means of the pivoted rock link 20 and themovement of the arm 38 is sotimed that prior to the deliveryof a printed sheet onto the platform 7the plates 36 and 39 are moved outwardly so as to allow plenty of roomfor the sheet to be deposited between the plates. After the sheet hasbeen deposited the plates move inwardly to properly position the sheeton the platform and to stack the sheets in a neat uni-form pile. litwill be apparentthat'upon movement ef the intense bar 19 the bar 22 willbe moved longitudinally in the guide collar 23 so as to impart move-'ment to the plate 36 operatively connected thereto.

As the printed sheets are piled on the platform 7 the increasing weightof the sheets will move the platform downwardly in the frame against thetension of the spring 11, so that a great many sheets may be piled ontothe platform 7 before it is necessary to remove them, and in a greatmany instances an entire job of printing maybe run through the pressbefore it is necessary to remove the sheets from the platform.

In order that the sheets may be readily removed from the platform 7 whendesired the bars 16 and 22 and the plate 37 together with the operativeparts may be swung on their pivots 17 and 23 to a raised position asshown in Figure 4. In raising bars 16 and 22 lifting power is applied tothe bar 22 and this bar carries a pin 44: which engages one of theflanges of the bar 16 for raising the two bars I simultaneously. Thusone side of the frame is opened to permit removal of the printed sheets.

It will be apparent from the foregoing that I have provided acomparatively simple and inexpensive device whereby a great many printedsheets can be delivered to the receiving table before it is necessary toremove them so as to save considerable time in printing and thenecessity of an attendant for removing these printed sheets whileoperating certain types of presses.

While I have shown and described the preferred embodiment of myinvention it willbe readily apparent that various changes andalterations may be made in putting my invention into practice withoutdeparting from the spirit of the invention or the scope of the appendedclaims.
